LiPo Battery Recovery
LiPo batteries are the heart of most RC models, but sometimes they go flat, won’t charge, or just don’t perform like they used to. Before you write them off as dead, there’s a good chance we can bring them back.
Our LiPo Battery Recovery Service gives tired packs a second chance. If your charger refuses to start, or a battery has dropped too low in voltage, we’ll safely test and attempt to recover it for you.
When to Consider Recovery
- The battery shows 0V or very low voltage
- Your charger won’t recognize it
- It feels weak or doesn’t deliver full power anymore
We use careful, controlled recovery methods to bring the voltage back to a safe level.
Important: If a battery is puffed or swollen, it can’t be recovered and must be safely disposed of.
Internal Resistance and Battery Health
Every LiPo has internal resistance (IR), measured in milliohms (mΩ). The lower the number, the better it performs. As batteries age or get stressed, the resistance goes up, and power drops off.
Once we’ve revived a battery, we test it to see how healthy it really is. The table below shows what the numbers mean in practical terms.
Internal Resistance Guide
| IR (mΩ per cell) | Health % | Condition |
|---|---|---|
| 0–5 | 100% | New, perfect performance |
| 5–10 | 98% | Excellent condition |
| 10–15 | 93% | Good, minor performance loss |
| 15–20 | 85% | Usable, some drop in punch |
| 20–25 | 75% | Still usable, mild voltage sag (Success) |
| 25–35 | 60% | Okay for low-power use (Customer choice) |
| 35–40 | 40% | Weak, not flight-ready (Customer choice) |
| 40+ | 20% or less | Unsafe, should be disposed (Customer choice) |
How the Process Works
1. Register Your Battery
Fill in the short online form to log your recovery request, then send or drop off your battery. You’ll find our address and contact details at the bottom of the website.
2. Recovery and Testing
We attempt recovery using controlled methods and then measure internal resistance, capacity, and voltage stability.
3. Report and Results
You’ll receive a simple report showing battery health, resistance readings, and our recommendation on whether it’s still safe for flying or only for low-power use.
4. Payment and Return
- If the battery tests at 75% health or higher, recovery was successful. The R150 fee applies plus shipping if we need to courier the battery back to you.
- If below 75%, no recovery fee applies. You can choose to have it shipped back (shipping only) or we can dispose of it safely for free.
Why Recovery is Worth It
- Costs far less than buying new batteries
- Better for the environment
- Gives you real data on your battery’s condition
Not every battery can be saved, but many can. It’s a quick, affordable way to find out what’s really going on before throwing it away.
Final Notes
The recovery service is meant to help extend the life of your packs, not replace buying new ones when they’re worn out. If a pack tests below 75% health, it’s no longer flight-safe but can still be used in ground or bench setups.
